Amnesia: The Dark Descent - Comment #241,712

Quoting what I said on Facebook:

This game isn’t scary when you watch videos. This game isn’t scary when you just wanna finish it. It’s scary when you fully immerse yourself within the game world. When you know that one errant twitch could land you face-to-face with a monster that isn’t aesthetically frightening in principle, but the moment causes your mind to squeeze every ounce of fright left in your body until all that’s left is a lifeless husk.

That, my friends, is Amnesia: The Dark Descent.
